BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 438,212, dated October 14, 1890.

Application tiled April 7, 1890. Serial No. 346,829. (No model.)

.To cir/ZZ whom t may concern:

Be it known that LGEORG WIssLER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Attachments to Turn In the Out Edges of Fabric-Binding; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to attachments for sewing-machines whereby they are put in condition to do some special work in addition to the ordinary sewing.

The special object of the attachment under consideration is to sew on binding cut o nt of cloth, cotton goods, and other similar fabrics. Binding` of this character, not having a selvage edge, like a so-called ribbon-binding, which has one, must have its edges turned in,in order to prevent them from fraying ont. Such out fabric-binding is in many cases cheaper than ribbon-binding, and also preferable in cases where it is desirable to have the binding of the exact shade and color of the balance of the material, and in which case the former is simply cut oft" in strips from the same material.

The specific construction of this attachment is fully explained in the following description and illustrated in the accompanying drawings, in which- Figure 1 is a perspective View, showing the attachment' in position and also adjacent parts of the sewing-machine. Fig. 2 is an end view of the attachment, showing its smaller end, the one which is turned toward the needle. attachment, the one remote from the needle. Fig. 4 is a section of the attachment, taken on a line 4 4 of Fig. 2 and looking to the left from this line. Fig. 5 is a central horizontal, and Fig. 6 is avertical section, of the attachment, taken on line 4 4 of Fig. 2 andlooking to the right from the said section-line. This latter view also shows the presser-foot in its relative position. Fig. 7 is a rear view of the presser-foot. Figs. 2 to 7 are enlarged.

Fig. 3 shows the larger end of theK 16 is the attachment, having a slotted lat-u eral extension 17, whereby it is held in position by means of a set-screw 18.

19 is the main body of the attachment, oonsisting of a funnel-shaped piece of sheet metal, having its side cut open and its out edges 2O bent at a pointindicated by 21 and turned in along a straight line passing through this point. These turned-in portions of the main body are not of equal width, as is most plainly shown in Fig. 5. y

22 is another piece of lnetal, bent semicircularly, its inner opening a little wider than its outer one, and its edges 23 reaching into the space between the main body 19 and its inturned edges 20, to the extreme innermost termination of which edges piece 22 isvconnected, preferably by soldering, and thus held in position. Y

24 is a guide-bar, by which the binding is forced to assume the proper shape and position within the attachment while being fed into it. The Widthof the binding cannot be more than the length of the space between this guide-bar and the main body of the attachment. It may, however, be alittle smaller.

The binding is preferably cut somewhat pointed, in order to facilitate at the beginning its introduction into the attachment. (See Fig. l.) Guide-bar 24 keeps the binding close against the inside of body 19, which by its convergen cy gradually turns its edges over and toward each other as the binding approaches the narrower exit end. This puts the binding in its proper position around the edge of the material which is to be bound, its edges not being turned in yet. Being, however, a binding cut in strips from larger pieces and having no' selvage edge, it becomes necessary to turn its cut edges in and sew them on in this position, in order to prevent their fraying out. The binding is so out that :its

width is in excess of the length of the discharge-mouth of the attachment, measured from one point 21 around to the other one. As a consequence, the edges of the binding, after having passed edges 23 of piece 22 and reached point 2l inside of the attachment, will be compelled to follow its inturned edges 20, and passing around edges 23 are iinally forced into the space between the infolded edges of the attachment and the corners 23 of piece 22. In this shape the binding is now delivered and sewed on, the needle l5 passing through the same in aposition as shown in Fig. 2, fully catching and securing its inturned edges. The thus doubled edges of the binding, as the latter passes from the attachment, are held up and kept constantly in proper position by the inner edges 23, which prevent the binding from receding or other- Wise passing out. from the path of the needle.

It is necessary to have the attachment not too close to the needle, for the reason that the ixnpperrhalt of the delivery-opening holds the "upper half of the binding somewhat up, and thus prevents the sewing-machine from draw- -ingthe stitch tight. Ii', however, placed somewhat away from-tbe needle, the paid-out binding has become sufficiently slack, so as not to interfere With the tension devices of the mafchine.

To lequalize'thepressure of the presser-foot von all parts of the-material as it passes through vthe .'machine, part of its under side or face has been cutaway to provide sufficient room for the increased thickness caused by the twice-doubled material of the bindingA (See Figs. ti'an'd Y7.) 1

The peculiar construction of this attach- 'mentm'akes it possible to use profitably bindving'of 'the nature described, inasmuch as it can be sewed on quickly and With one 'stitching, whereas nowthe'sewing on of such binding is such vatedious and laborious operation that it cannot beused with advantage. Iamv aware that there are binding attachments performing the same function, but they differ greatly in their specific construction, and in many cases are very complicated.

Having described my invention, I claim as neW 1. A binding attachment for the purpose of delivering binding in the proper shape and position, ready to be sewed onto the material to which it is to be attached, its deliveryopening being formed by the smaller end of a funnel-shaped piece of metal, which is open on its side and has its open edges turned inwardly, in combination With a U-shaped guide-piece supported Within the main body by the inturned edges of the latter in such a manner as to have its round portion concentric With the round part of the said main body and its t'ree sides parallel with the iiat sides of the former, said free sides reaching into the space between the main body and its inturned edges, substantially-as sho-Wn and described.

2. An attachment for turning in the edges of binding, consisting of the combination of a funnelshaped 'piece of metal open on its side and having its open edges turned in, las shown, an internal guide-piece supported'by the said inturned edges atand Within vthe delivery end and being substantially parallel and concentric With the main body, vand a guide-bar secured within the latter and at the receiving end of the attachment being also concentric with it and used for vthe 'purpose of supporting the in-feeding binding in proper shape, all as fully shown'a'nd described.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORG WIS'S'LER.
